Australia’s Greatest Mystery: The Somerton Man

A well-dressed man is found dead on an Australian beach with no identification, no known family, and a hidden scrap of paper reading “Tamám Shud” – “it is finished.” What followed became one of the strangest mysteries of the 20th century involving secret codes, missing labels, Cold War spy theories, and a question that haunted investigators for more than 70 years. This week, Michael Kent dives into the eerie true story of the Somerton Man. Then we play the Yap Yap Quiz with The Cosmic Romantics!

Human beings are unbelievably good at tolerating actual danger, but we are terrible at tolerating uncertainty. We will invent answers just to avoid saying “I don’t know.” That’s why conspiracy theories thrive. That’s why ghost stories survive. That’s why my family has a long-standing legend about an uncle pushing an aunt into the Grand Canyon and a couple times a year I go on a week-long google bender trying to solve the mystery. 

History is full of mysteries where the lack of an explanation became more compelling than the explanation ever could have been. The crew of the Mary Celeste vanished from their ship in 1872 and people immediately filled in the blanks with sea monsters, mutiny, insurance fraud, giant squid attacks, pirates, and supernatural nonsense. In reality, historians think there are several very reasonable explanations involving alcohol fumes or weather conditions, but reasonable explanations are boring. Giant squid are fun.

Then there was the disappearance of aviator Amelia Earhart. The moment her plane vanished, people started building myths around it. Some thought she’d been captured by the Japanese. Others thought she survived on a desert island. There are still documentaries every few years promising “the final answer,” which usually turns out to be somebody finding a blurry coconut or something.

And honestly, maybe that’s part of why mysteries endure. Once enough time passes, the mystery stops belonging to the people involved and starts belonging to the public imagination. We adopt them. We turn them into stories around a campfire. Every missing piece becomes an invitation.

That’s exactly what happened with the Somerton Man.

If you were trying to invent the perfect unsolved mystery, you’d probably come up with something very close to this. A dead man with no identification. Labels cut from his clothing. A cryptic message hidden in a secret pocket. A strange code that may or may not mean anything. Potential Cold War connections. Possible espionage. A mysterious nurse. An untraceable phone number. A rare book. Poison that may not leave evidence.

And for decades, nobody even knew the dead man’s name.

The story begins on December 1, 1948, in Adelaide. Specifically, on Somerton Beach, a quiet stretch of coastline southwest of the city center.

That evening, several witnesses noticed a man lying against the seawall on the beach. One couple saw him from a distance around 7 p.m. They later said he raised one arm weakly and then let it fall. Another witness saw him later in the evening and assumed he was drunk or asleep. Nobody thought much of it because people lying around on beaches was not exactly unusual.

The next morning, though, the man was still there.

At around 6:30 a.m., people realized something was wrong. The man was dead.

Police arrived and found a well-dressed man lying with his head propped against the seawall and his legs extended. He appeared to be around 40 to 45 years old, athletic, and in good physical condition. He wore a suit jacket, dress shirt, tie, trousers, polished shoes, and a sweater despite the warm weather. He had no hat, which was considered somewhat unusual at the time for a dressed-up adult man.

What immediately stood out to investigators was that the man carried no identification whatsoever. No wallet. No driver’s license. No passport. No papers.

Even stranger, every label had been carefully removed from his clothing.

Not some labels. All of them.

The labels had been cut out from his tie, his jacket, his trousers. Anything that could identify where the clothes came from or who owned them had been deliberately removed. That immediately raised suspicion because ordinary people do not go around surgically removing labels from every article of clothing they own.

The police searched his pockets. They found a bus ticket that had not been used. A used train ticket from Adelaide to the nearby suburb of Henley Beach. A pack of chewing gum. Cigarettes. Matches. But nothing revealing his identity.

The cigarettes themselves created another oddity. The box was an expensive brand called Kensitas, but inside were cheaper Army Club cigarettes. Investigators wondered whether that suggested someone refilled the pack to appear wealthier or whether it meant absolutely nothing at all.

At the autopsy, things got even stranger.

The pathologist found that the man’s pupils were unusually small and congested with blood. His spleen was enlarged. His liver showed signs of congestion. There was blood in his stomach mixed with food from a recent meal. The medical examiner concluded the man had likely died from heart failure.

But the doctor strongly suspected poison.

The problem was that toxicology tests found nothing.

Now today, when people hear that, they sometimes assume the testing was incompetent. But toxicology in 1948 was far more limited than modern forensic science. Certain poisons – especially some fast-acting alkaloids or digitalis-type substances – could potentially disappear or become difficult to detect. Investigators suspected poison largely because the physical symptoms fit poisoning better than natural causes.

And then there was the fact that the man appeared surprisingly healthy otherwise.

No signs of struggle. No obvious injuries. No indication of robbery. Just a healthy-looking man dead on a beach with all identifying information removed.

Police circulated photographs around Australia and internationally. Surely somebody would recognize him.

Nobody did.

That part is hard to overstate. Newspapers published the man’s face. His fingerprints were distributed. Investigators checked missing persons records. Sailors, immigrants, traveling businessmen, military personnel – everybody became a possibility. Yet nobody came forward with a positive identification.

Weeks passed.

Then investigators discovered something they had initially missed.

Inside the dead man’s trousers was a tiny hidden pocket sewn into the waistband. It was the kind of pocket tailors sometimes used for watches or small valuables. Inside that pocket was a tightly rolled scrap of paper.

On it were printed two words.

“Tamám Shud.”

Those words come from Persian and roughly translate to “ended” or “finished.” The phrase appeared on the final page of a famous collection of Persian poetry called The Rubaiyat of Omar Khayyam, a book that had become wildly popular in the English-speaking world during the late 19th and early 20th centuries.

Now suddenly this wasn’t just a dead man with no ID. This was a dead man carrying a hidden message that literally meant “it is finished.”

Which sounds less like real life and more like the opening scene of a detective novel written by somebody who was drinking absinthe.

Police released the phrase publicly, and eventually a man came forward saying he had found a copy of The Rubaiyat in his car around the time of the death. He had parked near Somerton Beach and discovered the book in the backseat after the body was found. He assumed someone had tossed it through an open window.

The final page had been torn out.

And that missing section perfectly matched the scrap of paper found in the Somerton Man’s pocket.

Inside the book, investigators discovered two additional mysteries.

The first was a phone number written in pencil.

The second was a strange sequence of letters that appeared to be some sort of code.

The code looked like random letters arranged in lines. Amateur cryptographers, military analysts, codebreakers, and hobbyists have spent decades trying to decipher it. Some believe it was an espionage code. Others think it was meaningless scribbling. Nobody has ever definitively cracked it.

Now if you’re police in 1948 and you find a dead unidentified man with a secret message hidden in his pants, a possible code, and an untraceable life, your brain starts going toward espionage pretty quickly.

And to be fair, this was exactly the right historical moment for people to think that way.

The Cold War was just beginning. Soviet espionage paranoia was growing worldwide. Australia had military facilities, weapons research sites, and growing strategic importance. People were already nervous about spies. Suddenly this mysterious dead man seemed to fit perfectly into that atmosphere.

The phone number written inside the book belonged to a nurse named Jessica Thomson, sometimes called Jo Thomson in reports.

And this is where the story somehow becomes even stranger.

Police interviewed her at her home in Glenelg, not far from Somerton Beach. When shown a plaster death mask made from the dead man’s face, witnesses claimed she appeared visibly shocked. Some investigators believed she nearly fainted. She denied knowing the man’s identity.

But there were odd connections.

Years earlier, during World War II, Jessica Thomson had given a copy of The Rubaiyat to an Australian army lieutenant named Alfred Boxall. Investigators briefly wondered whether the dead man was Boxall.

That theory collapsed when police located Boxall alive and well in Sydney. Even stranger, Boxall still possessed his copy of The Rubaiyat with the final page intact.

So now there were two Rubaiyats.

One belonged to a living military officer. The other was linked to a dead unidentified man.

Jessica Thomson denied knowing the dead man, though many investigators remained suspicious that she knew more than she admitted publicly. Over the years, speculation exploded around her role in the mystery. Some theorized she was a Soviet agent. Others believed she had a romantic relationship with the man. Some thought she was simply frightened and trying to avoid scandal.

There is no evidence proving any espionage connection. That’s important to say clearly because this story has accumulated decades of mythology.

Mythology loves empty space.

And this case had plenty of empty space.

Who was the Somerton Man? This story has a crazy twist.

Over the years, theories multiplied rapidly.

One of the earliest and most persistent ideas was espionage. Part of that came from timing. Part came from the code. And part came from geography. Adelaide was relatively close to the Woomera rocket testing range, a highly secretive military research site jointly operated by Australia and Britain. During the early Cold War, Woomera became strategically important for missile and weapons testing.

If you wanted to write a spy story in 1948 Australia, this was your setting.

Then there was the mystery code itself. The letters found in the back of The Rubaiyat appeared in several lines:

WRGOABABD
MLIAOI
WTBIMPANETP
MLIABOAIAQC
ITTMTSAMSTGAB

And then one crossed-out line beneath them.

Now cryptographers disagree about whether this was even a real cipher. Some believe it may simply represent initials from words in a poem or a mnemonic device. Others argue the patterns are too structured to be random. The code has been examined by naval intelligence, mathematicians, amateur sleuths, and computer scientists. No universally accepted solution has ever emerged.

That alone helped keep the mystery alive because humans are deeply uncomfortable with unresolved puzzles. Especially puzzles that look solvable.

It’s the same reason people obsessed over the Zodiac Killer ciphers or the Voynich manuscript. Once letters are arranged in a mysterious pattern, our brains become convinced meaning exists.

The Somerton Man case also became famous because of the bizarre collection of tiny details surrounding it. Each one individually could mean nothing. Together they created an atmosphere people couldn’t let go of.

For instance, the man’s calves were unusually developed. Some investigators suggested he may have been a ballet dancer, a runner, or somebody accustomed to wearing high-heeled boots. His toes supposedly formed a wedge shape sometimes associated with dancers.

That led to theories he was a performer.

Then there was the fact that his clothing seemed oddly mismatched for the climate and possibly American in style. Some reports claimed certain stitching patterns suggested American manufacture. Others disputed that entirely.

Some believed he was a sailor.

Some believed he was a displaced European immigrant.

Some believed he was a spy poisoned by enemy agents.

Some believed he killed himself.

The suicide theory grew stronger because of the Tamám Shud phrase itself. Since the phrase translates to “finished,” some investigators viewed it almost like a symbolic suicide note. The Rubaiyat of Omar Khayyam contains recurring themes about mortality, fate, and the fleeting nature of life. During the early 20th century, it had a reputation as a somewhat melancholy philosophical work.

If someone intentionally tore out the final phrase and carried it hidden in a secret pocket, that certainly feels deliberate.

But then the counterarguments appear.

If this was suicide, why remove all identifying labels? Why not leave identification? Why the possible code? Why the secrecy?

And if this was murder, why was there no evidence of struggle?

That tension is what made the Somerton Man one of the world’s great enduring mysteries. Every explanation solves one part while making another part stranger.

For decades, the case remained cold.

The man was buried in Adelaide’s West Terrace Cemetery in 1949. His gravestone read simply: “Here lies the unknown man.”

But interest in the mystery never disappeared.

Journalists revisited it every few years. Television programs covered it. Books analyzed it. Entire communities of amateur detectives formed around it long before internet sleuthing became common. Once the internet arrived, the Somerton Man became catnip for online mystery communities.

And like all famous mysteries, the internet made the story simultaneously better and worse.

Better because thousands of people brought fresh eyes and expertise to the case.

Worse because the story accumulated layers of exaggeration, myth, and outright invention.

For example, some modern retellings present the espionage theory almost as established fact. It absolutely is not. There is no hard evidence proving the Somerton Man was a spy.

But there are interesting coincidences.

Jessica Thomson lived near Somerton Beach. Her son Robin reportedly shared some physical traits with the dead man including unusual ears and teeth patterns. Some people theorized Robin may have been the Somerton Man’s biological child.

That possibility became one of the biggest developments in the case decades later.

A professor named Derek Abbott from the University of Adelaide became deeply interested in the mystery in the 2000s. Abbott eventually developed a relationship with the Thomson family and later married Rachel Egan, Jessica Thomson’s granddaughter.

Which means a man investigating the Somerton mystery ended up marrying into the family connected to the mystery.

Again, if you wrote this in fiction, an editor would tell you to calm down because it sounds too dramatic.

Abbott became one of the leading advocates for exhuming the Somerton Man’s body to obtain DNA.

For years, Australian authorities resisted. But eventually, advances in forensic genealogy changed the landscape entirely. Cases once thought impossible suddenly became solvable through distant DNA relatives and genealogical databases.

In 2021, the body was finally exhumed.

Scientists extracted DNA samples, and in 2022, researchers announced what appeared to be a major breakthrough.

The Somerton Man was likely a man named Carl “Charles” Webb.

Webb was an electrical engineer born in Melbourne in 1905. He had separated from his wife Dorothy years earlier and seemingly disappeared from public records. Genealogical analysis strongly suggested the unidentified body matched Webb’s family line.

Now importantly, some authorities and researchers have been cautious in describing the identification as absolutely final, but the DNA evidence appears highly persuasive and is widely accepted by many investigators today.

So after more than 70 years, the Somerton Man may finally have a name.

Carl Webb.

But if you’re thinking that identification solved everything, it really didn’t.

It solved one enormous mystery while leaving several others intact.

Because now we know who he likely was. But we still don’t fully know why he died, why he was in Adelaide, why the labels were removed, why he carried the Tamám Shud scrap, or what role – if any – Jessica Thomson played in his life.

Researchers discovered Webb had a background connected to engineering and instruments, which some people argue could fit the espionage theory. But again, that’s speculative.

Others believe the simplest explanation remains most likely. Webb may have traveled to Adelaide seeking Jessica Thomson, with whom he may have had a past relationship. He may have been emotionally distressed. He may have taken poison intentionally. The labels may have been removed to avoid identification and shame.

That theory explains many elements.

But not all of them.

And the unresolved details are exactly why this story refuses to die.

The Somerton Man mystery sits at the perfect intersection of noir detective fiction, Cold War paranoia, romantic tragedy, and forensic science. It contains just enough answers to feel grounded and just enough missing pieces to remain haunting.

There’s also something uniquely eerie about how ordinary the beginning of the story was. A man lying on a beach. Witnesses assuming he was sleeping. Nobody realizing they were looking at one of the most famous unidentified bodies in modern history.

That’s another reason this case endures. It reminds us how thin the line is between ordinary life and mystery.

For decades, Carl Webb – if that was indeed the Somerton Man – existed almost like a ghost. A person disconnected from history. No identity. No family. No past.

And then science slowly reached backward through time and tugged him partially back into the world.

I think that’s why people became emotionally invested in the case beyond the spy theories and cryptic notes. At its core, the story is about identity. About whether a person can disappear completely. About whether the world eventually remembers you.

Because for over 70 years, this man was known only by where he died. Not who he was. That’s haunting.

And there’s another uncomfortable aspect to the story. Even after the probable identification, some experts remain skeptical about parts of the evidence trail. The original investigation happened in 1948. Evidence handling was not what it is today. Records disappeared. Witness memories shifted. Important objects were lost. The suitcase believed connected to the Somerton Man vanished at one point from police storage.

Which means some questions may never be answered conclusively.

Maybe the code really means something.

Maybe it doesn’t.

Maybe the Tamám Shud message was deeply symbolic.

Maybe it was coincidence amplified by human imagination.

Maybe Carl Webb was a spy.

Maybe he was simply a lonely man who died far from home.

The truth is that real life rarely ties itself into perfect narrative bows. Mysteries do not exist for our entertainment. They exist because humans are messy, records are incomplete, witnesses forget things, and sometimes people vanish between the cracks of history.

But every once in a while, a mystery becomes larger than the facts themselves.

The Somerton Man became one of those mysteries.

A dead man on a beach became a global obsession. Newspapers, books, documentaries, internet forums, codebreakers, genealogists, and conspiracy theorists all circled around the same haunting question for generations.

Who was he?

And in the end, after decades of speculation involving spies, poison, secret lovers, and Cold War intrigue, the answer may have been both less glamorous and more human than anyone expected.

He may simply have been Carl Webb.

A real person.

A complicated person.

A forgotten person.

And somehow, that ending feels sadder than any spy thriller ever could.

Once you remove all the mythology, you’re left with a lonely truth. Somebody died on a beach in 1948, and for most of the next century, nobody knew his name.

The internet says it’s true.
